each THREE drop in 'x' drops y by 1.5

soooo

6/1.5 = 4        so we need to drop 4*3 = 12  from 2    to   -10

y changes  by  1.5   when  x changes  by   3

 

So....the  slope of  this linear  finction is     1.5   / 3   =  1/2

 

Since   (2,6)  is on the  graph   we  have  this linear equation 

 

y= (1/2) (x - 2 )  +  6      simplify

 

y=  (1/2)x  - 1  +  6

 

y = (1/2) (x)  +  5

 

When y  = 0   we  have  that

 

0  = (1/2)x  + 5

 

-5  = (1/2)x

 

x = -5 / (1/2)  =  -5 * 2/1  =   -10      when y  =  0

 

 

cool cool cool
